Jerome's Radeon KMS Short-Term TODO List

Phoronix: Jerome's Radeon KMS Short-Term TODO List

After the earlier X talks today and then Luc's debated Linux graphics driver stack proposal (largely between he and Eric Anholt and Daniel Stone with conflicting views, but at least Intel admitting "there's a subset of users we care about and a subset we don't"), Jerome Glisse began talking about ATI Radeon kernel mode-setting and its current state. While most that read Phoronix regularly know the direction of Radeon KMS support for the coming releases, below is Jerome's short-term TODO list for the ATI kernel support. Coming up in the Radeon DRM for the Linux 2.6.34 kernel (or releases thereafter) is support for un-mappable VRAM, support for Evergreen GPUs (Radeon HD 5000 "R800" series), use of the Linux power management API for better suspend-and-resume support, better DRM power management, HDMI audio for R700/800 graphics processors, and improved GPU lock-up recording. Other plans on the code side include better fence for improved lock-up detection, using union to separate ASIC specific data, and better message prints for multi-GPU configurations. The most common kernel mode-setting problems these days for ATI Radeon customers is coming down to mode detection issues, PLL issues on laptops with Mobility Radeon parts, ACPI/BIOS interaction problems, memory fragmentation, command submission issues, and GPU lock-ups...
